25.37 · European Light Bulb. In Europe the standard voltage in homes is 220 V instead of the 120 V used in the United States. Therefore a “100-W" European bulb would be intended for use with a 220-V potential difference (see Problem 25.36). (a) If you bring a “100-W" European bulb home to the United States, what should be its U.S. power rating? (b) How much current will the 100-W European bulb draw in normal use in the United States?
